Effect: Pause button works, but play button doesn't, so videos can't be played once paused (or if not started due to 'Auto play (video)' option being disabled)

To reproduce:
1. Open video file
2. If video auto plays, pause it, at which point it can't be resumed. If it doesn't auto play, it can't be started.
Actual behaviour (bug): XnView won't play video files except automatically
